How to Use a Table of Start &amp; End MP to be displayed on LRS

I am trying to find out if there is a way to use a table (web published .csv file) that contains a list of start and end route and mileposts and display the events as a polyline on an established linear reference system (LRS). I want to be able to maintain a link from the table so that when the table is updated, the map will be updated as well. Any suggestions out there?
